Maybe they are prioritizing the health of the athlete/wrestler today. You cannot compare football to wrestling. In football, lose one game and it can impact bowl games, playoffs, etc. In wrestling, you just have to qualify for NCAA's and you can be a National Champion.
I understand the frustration, we the fans want to see good competition. I coach high school track, there are meets where we are looking/anticipating good competition to test our kids and push them. It turns out the other schools in the meet have an Invitational on Saturday and send their JV. It sucks.
When you look at the current wrestling coaching staffs, filled with guys who wrestled lots of matches in their careers, they might just know something if they are intentionally reducing the number of matches they have their wrestlers wrestle. This is done mostly by reducing the number of tournaments they attend and Jimmy Kennedy addressed this.
That being said, as others have pointed out, these "big dual" meets should not be scheduled late in the season.
